Compartmentation is one of the most important concepts in fire safety. Compartment walls create a barrier to the growth of fire, avoiding fire to expand to the next compartment and to the whole building. They are also essential to create safe shelters for the people. In many cases existing walls of different nature and materials can be upgraded to be an efficient fire compartment barrier. CHAR 21 is used to achieve fire resistance of up to 120 minutes on many common non-loadbearing walls made of masonry bricks or concrete blocks according to the European Standard EN 1364-1.
CHAR 21 waterborne intumescent paint for fire protection of steel structures, concrete and reinforced concrete structures, masonry and concrete partitioning walls, wood surfaces and in other application fields.
